BACKGROUND

1. Field

Apparatuses consistent with exemplary embodiments relate to an apparatusof receiving and discharging a material, and more particularly, to anapparatus or receiving and discharging waste vinyl on a constantquantity basis.

2. Description of the Related Art

In general, a mounter for mounting components is usually used inautomatically mounting electronic components, such as semiconductorchips, condensers or resistors, on a printed circuit board (PCB).

A tray feeder or a tape feeder may be used to supply components to themounter. The components to be mounted on the PCB are transferred to acomponent pick-up position of the mounter under the control of acontroller provided in the feeder, and the mounter picks up thetransferred components in a predefined order to mount the picked upcomponents on the PCB.

An electronic component supply apparatus, such as a feeder used in amounter for mounting components, continuously supplies the components.Surfaces of the components to be mounted are coated with a material,such as vinyl, for protecting the components before the components aremounted, and the protecting material such as vinyl is peeled offimmediately before the components are supplied to the mounter to besupplied to the mounter.

One method for disposing of waste vinyl peeled off from the componentsupply apparatus is to roll up the waste vinyl on a constant quantitybasis to collectively dispose of the waste vinyl. Another method fordisposing of waste vinyl peeled off from the component supply apparatusis to discharge waste vinyl downward or rearward with respect to thecomponent supply apparatus in an endless discharge manner.

In the waste vinyl disposal system, the waste vinyl is exposed to theoutside, which may create unpleasing external appearance in workingconditions. In particular, in the latter case, since the waste vinyl iscontinuously discharged, it is necessary for an operator to stay at awaste vinyl outlet to perform a waste vinyl disposal operation withoutinterruption, which requires an unnecessary labor force and increasesmanufacturing costs.

SUMMARY

One or more exemplary embodiments are provided to address the foregoingproblems, and an object of the these exemplary embodiments is to providean apparatus for disposing of waste vinyl, which can improve externalappearance in working conditions by receiving the waste vinyl in apredetermined space and automatically discharging on a constant quantitybasis to allow an operator to dispose of the discharged waste vinyl, andcan reduce an operator's working time required for the operator toperform a waste vinyl disposal operation.

One or more exemplary embodiments also provide an apparatus fordisposing of waste vinyl, which includes a pressure transmitting part,which can prevent waste vinyl from flowing backward due to an abnormalincrease in an internal pressure of a predetermined space for receivingthe waste vinyl when the waste vinyl is received in the predeterminedspace, thereby enhancing reliability in a waste vinyl disposaloperation.

Although the exemplary embodiments described in detail in the presentapplication are directed to an apparatus for disposing of waste vinyl,the inventive concept is not limited thereto.

According to an aspect of an exemplary embodiment, there is provided anapparatus of receiving and discharging a material, the apparatusincluding a receiving part which receives a material supplied from anoutside; a supply part which is provided at an end of the receivingpart, through which the material is supplied to the receiving part; adoor part which is provided at another end of the receiving part andconfigured to be opened to the outside; and a fixing part which isprovided at a location adjacent to the door part and maintains thereceiving part in a closed state until an internal pressure of thereceiving part reaches a predetermined pressure level, wherein the doorpart is opened to discharge the material to the outside if the internalpressure of the receiving part exceeds the predetermined pressure level.

The apparatus for disposing waste vinyl may further include a pressuretransmitting part provided at one side of the receiving part andconfigured to be shifted by the internal pressure of the receiving partso that one end of the pressure transmitting part to contact the doorpart to open the door part to the outside.

Hereinafter, an apparatus for disposing of waste vinyl according to anexemplary embodiment will be described with reference to FIGS. 1 to 3.FIG. 1 is a schematic diagram of an apparatus for disposing of wastevinyl according to an exemplary embodiment, FIG. 2 illustrates that adoor part is automatically opened to discharge waste vinyl on a constantquantity basis when greater than a predetermined quantity of waste vinylis received in the apparatus for disposing of waste vinyl shown in FIG.1, and FIG. 3 illustrates an operation failure occurring when a doorpart is not opened even with an increase in the internal pressure of theapparatus for disposing of waste vinyl shown in FIG. 1.

The waste vinyl disposal apparatus 10 according to an exemplaryembodiment includes a receiving part 11 having an empty space to receivethe waste vinyl V, a supply part 12 provided at an end of the receivingpart 11 and supplying the waste vinyl V to the receiving part 11, a doorpart 13 provided at the other end of the receiving part 11 andconfigured to be opened to the outside along a rotation shaft, and afixing part 14 formed at a location adjacent to the door part 13. Thefixing part and the door part 13 are configured to maintain thereceiving part 11 in a closed state until an internal pressure of thereceiving part 11 reaches a predetermined pressure level.

Referring to FIG. 1, the receiving part 11 is an empty space to receivethe waste vinyl V and is configured to open the door part 13 by pressingthe door part 13 to the outside by the internal pressure as the internalpressure gradually increases. Therefore, the receiving part 11 may be asealed space so as to increase the internal pressure to be maintained ata constant level.

The supply part 12 is formed at the end of the receiving part 11. Thesupply part 12 supplies the waste vinyl V to the receiving part 11. Thesupply part 12 may include a pair of rollers meshed with each other androtating so as to supply the waste vinyl V to the inside of thereceiving part 11 while maintaining a sealed state of the receiving part11. Therefore, while the receiving part 11 is maintained insulated fromthe outside, it may supply the waste vinyl V to the inside of thereceiving part 11.

The door part 13 is formed at the other end of the receiving part 11.The door part 13 is provided to be opened to the outside along therotation shaft. If greater than the constant quantity of waste vinyl Vis supplied to the inside of the receiving part 11, the internalpressure of the receiving part 11 is increased by the waste vinyl V, bywhich the door part 13 is opened to the outside, as shown in FIG. 2, sothat a pile of waste vinyl V may be discharged at the same time. Theoperator can easily process the pile of waste vinyl V discharged on aconstant quantity basis for a predetermined time. Since the door part 13is closed in other times in which waste vinyl V is not discharged, theoperator may perform another operating work while the waste vinyl V isnot discharged, thereby increasing working efficiency.

The door part 13 is and the fixing part 14 are configured to maintainthe receiving part at a closed state, and, when the internal pressureexceeds the predetermined level, it is opened to the outside because aforce of opening the door part 13 to the outside exceeds a force offixing the door part to the fixing part 14. As shown in FIG. 1, thefixing part 14 is formed at a location adjacent to one side of the doorpart 13.

The receiving part 11 should be maintained at the closed state until theinternal pressure reaches the predetermined level, and then, be openedwhen the internal pressure exceeds the predetermined level. Thus, thefixing part 14 may be formed of, for example, a magnetic material, so asto fix the door part 13 with a uniform force corresponding to theinternal pressure. That is, the receiving part 11 is maintained at theclosed state due to an attraction applied between the fixing part 14 anda metal support formed at one side of the door part 13, and when theinternal pressure becomes greater than the attraction, the door part 13may be opened to the outside over the attraction. In the illustratedembodiment, the fixing part 14 is formed at a location spaced apart fromthe rotation shaft of the door part 13, but aspects of the inventiveconcept are not limited thereto.

As described above, if the door part 13 is opened to the outside, thepile of waste vinyl V is discharged on a constant quantity basis at thesame time. The operator easily treats the discharged pile of waste vinylV for a predetermined time, and the door part 13 is again closed toallow the receiving part 11 to receive again the waste vinyl V.

Referring to FIG. 3, in this embodiment, opening or closing of the doorpart 13 depends only on the internal pressure of the receiving part 11.However, as shown, when internal pressures of the receiving part 11 aredifferent between the door part 13 and the supply part 12, the internalpressure of the receiving part 11 may not be properly transmitted to thedoor part 13.

That is, since a pressure from the waste vinyl V is applied in only onedirection, the pressure may not be sufficiently transmitted to the doorpart 13 according to the direction and shape of the waste vinyl V piledin the receiving part 11. Thus, the door part 13 is not opened but thepressure of the supply part 12 gradually increases. Accordingly, thewaste vinyl V is highly likely to get jammed or to flow backward.

In particular, since there is a big difference in the pressuretransmitted to the door part 13 relative to the quantity of waste vinylV piled in the receiving part 11 according to the type and adhesion ofthe waste vinyl V, the weather or the humidity, there may be a problemthat the door part 13 is not opened even if the quantity of waste vinylV exceeds a predetermined level of quantity to be received.

Thus, in case where the door part 13 is not opened, an auxiliarycomponent may become necessary, which will be described in detail withreference to FIGS. 4 and 5. FIG. 4 is a schematic diagram of anapparatus for disposing of waste vinyl according to another exemplaryembodiment, and FIG. 5 illustrates operating mechanism depending on anincrease in the internal pressure of the apparatus for disposing ofwaste vinyl shown in FIG. 4.

The waste vinyl disposal apparatus 10 includes a receiving part 11having an empty space to receive the waste vinyl V, a supply part 12provided at an end of the receiving part 11 and supplying the wastevinyl V to the receiving part 11, a door part 13 provided at the otherend of the receiving part 11 and configured to be opened to the outsidealong a rotation shaft, a fixing part 14 formed at a location adjacentto the door part 13 to maintain the receiving part 11 in a closed stateuntil an internal pressure of the receiving part 11 reaches apredetermined pressure level, and a pressure transmitting part 15provided at one side of the receiving part 11 and including a pressuresensing unit 15 a provided adjacent to the supply part 12 and a pressingunit 15 b provided adjacent to the door part 13. The pressure sensingunit 15 a is shifted by the internal pressure of the receiving part 11,and the pressing unit 15 b is moved to the door part 13 by the pressuresensing unit 15 a to press the door part 13 to the outside, therebyallowing the door part 13 to be opened.

Unlike in the previous embodiment, the waste vinyl disposal apparatusaccording to this embodiment may further include the pressuretransmitting part 15. That is, the pressure transmitting part 15, whichis formed at one side of the receiving part 11 and has one endpositioned adjacent to the door part 13, senses the internal pressure ofthe receiving part 11 and is configured to move in a lengthwisedirection of the receiving part 11 by the internal pressure of thereceiving part 11.

As shown in FIG. 4, when the quantity of waste vinyl V received in thereceiving part 11 is less than a predetermined quantity, the internalpressure of the receiving part 11 is maintained at the predeterminedlevel or less, so that the pressure transmitting part 15 is not movedtoward the door part 13. In this case, as described above, the fixingpart 14 keeps the door part 13 at a closed state.

However, as shown in FIG. 5, when the quantity of waste vinyl V receivedin the receiving part 11 is greater than a predetermined quantity, theinternal pressure of the receiving part 11 increases to a predeterminedlevel or higher, so that the pressure transmitting part 15 is movedtoward the door part 13 and pushes the door part 13 away to the outside.Here, a force of fixing the door part 13 to the fixing part 14 isgreater than a force applied to the door part 13 to the outside by theinternal pressure of the receiving part 11. Since, however, a sum of theforce applied to the door part 13 to the outside by the internalpressure of the receiving part 11 and a force applied to the door part13 by the pressure transmitting part 15 pressing the door part 13 to theoutside is greater than the force of fixing the door part 13 to thefixing part 14, the door part 13 may be opened to the outside.

The pressure sensing unit 15 a is configured to protrude toward theinside of the receiving part 11 so as to sense the internal pressure ofthe receiving part 11. That is, the pressure sensing unit 15 a shaped ofa protrusion is pressed toward the door part 13 by the internal pressureof the receiving part 11.

The pressing unit 15 b is connected to the pressure sensing unit 15 aand extends in one direction to be positioned adjacent to the door part13. Therefore, if the pressure sensing unit 15 a is pressed toward thedoor part 13, the pressing unit 15 b is also pressed toward the doorpart 13, thereby allowing the door part 13 to be opened.

The pressure transmitting part 15, specifically, the pressure sensingunit 15 a may be formed adjacent to the supply part 12 in the receivingpart 11. That is, as described above, when the internal pressure of thereceiving part 11 is not uniformly maintained, the internal pressuretends to increase toward the supply part 12. Since the internal pressureis not directly transmitted to the door part 13, the door part 13 maynot be opened even if the partial internal pressure of the receivingpart 11 positioned adjacent to the supply part 12 is greatly increased.

Therefore, in a case where the pressure sensing unit 15 a is formedadjacent to the supply part 12 in the receiving part 11 to make the doorpart 13 opened, a high internal pressure of the receiving part 11 may betransmitted to the door part 13 through the pressing unit 15 b.Therefore, even if the internal pressure around the door part 13 ismaintained at the predetermined level or less, the door part 13 may beopened when the partial internal pressure of the receiving part 11positioned adjacent to the supply part 12 becomes greater than or equalto the predetermine level.

Accordingly, abnormalities occurring when the door part 13 is not openeddue to non-uniform distribution in the internal pressure, such asjamming or backward flow of the waste vinyl V, may be avoided.

The inventive concept does not limit the configuration of the pressuretransmitting part 15 to the exemplary embodiment illustrated herein, andthe pressure sensing unit 15 a and the pressing unit 15 b may beintegrally formed. The pressure sensing unit 15 a may be formed of athin and wide panel so as to allow the internal pressure to be easilytransmitted to the door part 13. In addition, the pressing unit 15 b maybe shaped of a pipe capable of pressing the door part 13 to the outside.In addition, the pressure sensing unit 15 a and the pressing unit 15 bmay be formed in a combination of a piston and a cylinder, a piston anda rod, or the like.

Hereinafter, an apparatus for disposing of waste vinyl according tostill another exemplary embodiment of the present invention will bedescribed with reference to FIGS. 6 and 7. FIG. 6 is a schematic diagramof an apparatus for disposing of waste vinyl according to still anotherexemplary embodiment of the present invention and FIG. 7 illustratesoperating mechanism depending on an increase in the internal pressure ofthe apparatus for disposing of waste vinyl shown in FIG. 6.

Like in the previous embodiment, the waste vinyl disposal apparatusaccording to this embodiment includes a pressure transmitting part 15.However, the pressure transmitting part 15 according to this embodimentoperates in a different manner than in the previous embodiment. That isto say, the pressure transmitting part 15 may be an elastic member thatsenses a pressure and has a length varying in a lengthwise direction.

In detail, the pressure transmitting part 15 is provided at one side ofthe receiving part 11, and has one end fixed to one surface of thereceiving part 11 and the other end positioned adjacent to the door part13. Here, a hinge part 16 may be provided at the end of the pressuretransmitting part 15 adjacent to the door part 13. The hinge part 16 maybe connected to the pressure transmitting part 15, and may guide amovement direction of the pressure transmitting part 15 due to elasticdeformation.

The pressure transmitting part 15 may have a convex section protrudingtoward an internal space of the receiving part 11.

The internal space of the receiving part 11 is filled with waste vinylV. If the internal space of the receiving part 11 is filled with greaterthan a predetermined quantity of waste vinyl V, a pressure of theinternal space increases and the waste vinyl V presses the convexsection of the pressure transmitting part 15. Since the pressuretransmitting part 15 is formed of an elastic member, when a pressure ofa predetermined level or greater is applied to the pressure transmittingpart 15, a protruding height of the convex section may be reduced. Sincethe one end of the pressure transmitting part 15 is fixed, the pressuretransmitting part 15 is elongated in the lengthwise direction toward thedoor part 13 by a length corresponding to the protruding height of theconvex section, so that the other end of the pressure transmitting part15 is moved toward the door part 13.

Deformation of the pressure transmitting part 15 gradually increases andthe pressure transmitting part 15 continuously presses the door part 13.Then, if a sum of a force applied to the door part 13 to the outside bythe internal pressure of the receiving part 11 and a force applied tothe door part 13 by the pressure transmitting part 15 pressing the doorpart 13 to the outside exceeds a force of fixing the door part 13 to thefixing part 14, the door part 13 is opened to the outside, as shown inFIG. 7.

Therefore, even if the internal pressure around the door part 13 ismaintained at the predetermined level or less, the door part 13 may beopened when the internal pressure applied to the pressure transmittingpart 15 exceeds the predetermined level. Accordingly, abnormalities,such as jamming or backward flow of the waste vinyl V, occurring whenthe door part 13 is not opened due to non-uniform distribution in theinternal pressure may be avoided.

Hereinafter, an apparatus for disposing of waste vinyl according tostill another exemplary embodiment will be described with reference toFIGS. 8 and 9. FIG. 8 is a schematic diagram of an apparatus fordisposing of waste vinyl according to still another exemplary embodimentof the present invention, and FIG. 9 illustrates operating mechanismdepending on an increase in the internal pressure of the apparatus fordisposing of waste vinyl shown in FIG. 8.

Like in the previous embodiment, the waste vinyl disposal apparatusaccording to this embodiment includes a pressure transmitting part 15.However, the pressure transmitting part 15 according to this embodimentoperates in a different manner than in the previous embodiment, and adoor part 13 is fixed by a fixing part 14 in a different manner than inthe previous embodiment.

That is, the pressure transmitting part 15 is fixed to one surface ofthe receiving part 11 by a hinge part 16 around the center thereof, andis rotatably installed about the hinge part 16. An end of the pressuretransmitting part 15 positioned adjacent to the door part 13 is bent ina predetermined direction and is in mesh with an end of the door part13, forming the fixing part 14.

As shown in FIG. 9, if waste vinyl V is piled up in an internal space ofthe receiving part 11, an internal pressure of the receiving part 11increases, and a bottom surface of the rotatably installed pressuretransmitting part 15 is pressed by the internal pressure. The pressedpressure transmitting part 15 rotates about the hinge part 16. If thepressure transmitting part 15 is rotated by a predetermined length orlonger, one end of the pressure transmitting part 15 and one end of thedoor part 13, which form the fixing part 14, are separated from eachother to allow the door part to be opened to the outside.

To this end, with respect to the hinge part 16, a first region of thepressure transmitting part 15 (a left portion in FIG. 8) is brought intoclose contact with one surface of the receiving part 11 (a top portionin FIG. 8) and a second region of the pressure transmitting part 15 (aright portion in FIG. 8) is spaced apart from the one surface of thereceiving part 11 (the top portion in FIG. 8). The pressure transmittingpart 15 in the second region is provided to be rotatable toward onesurface of the receiving part 11 (counterclockwise in FIGS. 8 and 9.

Therefore, even if the internal pressure around the door part 13 ismaintained at a predetermined level or less, the door part 13 may beopened when the internal pressure around the supply part 12 is greaterthan or equal to the predetermine level. Accordingly, abnormalitiesoccurring when the door part 13 is not opened due to non-uniformdistribution in the internal pressure, such as jamming or backward flowof the waste vinyl V, may be avoided.

For example, theapparatuses described in the exemplary embodiments may not be limited toonly those apparatuses disposing of waste vinyl.
